What makes something sink or float?
Objective: Students will collect data when they investigate what objects sink or float.
Boat engineers collect data about if materials sink or float before they build a boat. How can you collect the data to tell which objects sink or float?
PROCEDURE
1. Choose one object and observe it. Record the name of the object in your observations in the chart.
2. Predict whether the object will sink or float when placed in a bin of water.
3. Gently place the object over the water in the bin and let go of it.
4. Observe whether the object sinks or floats. Record your observations in the chart.
5. Repeat the process with three other objects. Record all information in the chart.
